SASH-LOCK, LIFT, AND SASH-SUPPORTR.

SPECIFICATION forming part of Letters Patent No. 734,855, dated July 28, 1903.

Be it known that I, LOUIS W. HAGEL,a citizen of the United States,residing at Jacksonville, in the county of Morgan and State of Illinois, have invented certain new and useful Improvements in Sash-Locks, Lifts, and Sash- Supporters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled morti sed in the sash to disengage the bolt from.

the rack when the window is raised.

My invention is primarilyT designed for carwindows, where a positive lock is required to maintain the window in an elevated position to prevent it being jarred bythe motion of the train.

With these objects in view important details of construction have necessarily to be devised, and it is these features also that I will hereinafter describe in detail and particularly point out in the claim. In the drawings, Figure l is a front elevation of a window, illustrating the application of my invention to a heavy window. Fig. 2

is a similar view illustrating the application of the invention to a small window. Fig. 3

and the lift.

Fig. ,Tis a top plan view of the same. Fig. 8 is a detail perspective view of the lock-bolt. Fig. 9 is an enlarged frontelevation of the housing Fig. l is a detail viewshowing the locking-shoulder at the end of rack-bar 3.

The same numerals refer to like parts in all the figures.

l represents a window-frame of ordinary construction having the usual sash-guide 2. In the face of the guide is a rack-bar 3, whose teeth incline upwardly and which is provided at its lower end with a shoulder 4, against 5 5` which the locking-bolt is seated when the window is down.

Preferablyin the lower rail of the sash 6 is a mortise 7 to receive a housing 8. The

housing is composed of a rearwardly-extend- 6o ing box-like structure 9 open at its top and. having in one of its side walls a bearing l0. The front Vwall ll of the housing has an opening l2 for the convenient insertion of a persons fingers, and over the opening is an out- 65 wardly-proj ecting flange 13.

l5 represents an opening in the sash, which extends to the outer edge thereof from and in alinement with the bearing l0. A bushing 16 is interposed in the outer end of the open- 7o ing to form the opposite bearingfor the bolt.

17 represents the bolt, having at one end an annular groove IS to form a neck, and 19 indicates the lift. formation and is pivoted within the housing 8 at 20. The lower end of the vertical leg 2l of the lift is slightly reduced and is bifurcated at 22, while the horizontal member 23 of said lift is slightly beveled at its rear 24 to avoid 80 frictional resistance when in operation. A spring 25 is interposed between the top of the mortise and the member 23 to prevent the parts rattling an dincidentally force the bolt The bolt is placed in the opening l5,

out. being guided in the bearings l0 and 16, the end havin gthe groove 18 being in the housing. The bifurcated end 22 of'thelift engages the neck adjacent the groove 18, and the pivot 2O is placed in position, completing the assem- 9o engagement with the stop at the lower end of `rco the rack 3. The sash is now free to be moved upward until the desired height is reached,

The lift is of right-angular 75 Pressure upward is` `exerted to whereuponpressure on the lift is released,`

and under the influence of the spring 25 and v the weight of the lift the bolt is forced outwardly and engages one of the teeth of the rack, thus supporting the window at any desired point. I have described a spring for incidentally returning the bolt to its normal position. However, its prime function is to prevent rattling of the parts when the inven tion is applied to windows of railway-cars; but for ordinary use the weight of the lift is sufficient to return the bolt, so that I do not desire to limit myself in this particular.

When the improvement is applied to large windows, there will be one lock and lift located near both edges thereof, as disclosed in Fig. l; but for windows of ordinary sizes one lock will be found sufficient.

My invention is extremely simple and possesses decided advantages over the prior art, inasmuch as the parts are arranged whereby the holding action is positive and the necessary movement to make it such does not require a further operation other than the mere raising of the window.

What I claim as new is-V In a sash-lock, the combination with a window-frame, of a rack secured thereto, a win-4 dow-sash having a mortise therein, a housing LOUIS W. HAGEL.
